Three storms are examined to determine the contribution to the Dst* index from the symmetric and asymmetric (partial) components of the ring current. The storms (September 24–25, 1998, October 18–19, 1998, and May 14–15, 1997) all have a similar solar wind trigger (an initial shock followed by a coronal mass ejection with southward interplanetary magnetic field) and placement in the solar cycle (rising phase). The near-Earth ion distribution function is simulated for each storm using a kinetic… Expand
Small-Scale Structure in the Stormtime Ring Current
The partial ring current tries to limit itself through the electric field associated with the ionospheric closure currents. The relationship between the hot ion pressure peak and the electricExpand
Ring current simulations of the 90 intense storms during solar cycle 23
[1] All of the intense magnetic storms (minimum Dst value of <−100 nT) from solar cycle 23 (1996–2005) were simulated using the hot electron and ion drift integrator (HEIDI) model. The simulationsExpand

The Storm‐Substorm Relationship: Current Understanding and Outlook
The intensification of the ring current during a geospace storm has been one of the key issues in space physics. Substorms have been considered responsible for bringing in particles from theExpand
Computational analysis of the near-Earth magnetospheric current system during two-phase decay storms
Several two-phase decay magnetic storms are examined using a kinetic transport model to find the spatial and temporal distribution of the perpendicular and field-aligned currents in the innerExpand
Discussion paper: Partial ring current and polarization jet
[1] We analyze the asymmetric part of the ring current (RC), which appears during the main phase of a magnetic storm and is due to strong precipitation of RC ions into the ionosphere. TheExpand
Relation between the ring current and the tail current during magnetic storms
We study the dynamics of the magneto- spheric large-scale current systems during storms by using three different magnetospheric magnetic field models: the paraboloid, event-oriented, and TsyganenkoExpand
A model‐derived storm time asymmetric ring current driven electric field description
[1] Low-latitude ionospheric and near-Earth magnetospheric electric fields are calculated from model results of the storm time asymmetric ring current. These fields are generated from subauroralExpand
Contribution of the partial ring current to the SYMH index during magnetic storms
To identify which magnetospheric current system contributes the most to the SYMH index during magnetic storms, we performed a statistical analysis of 299 magnetic storms from 1996 to 2006 andExpand

Are our ideas about Dst correct?
The idea of two separate storm time ring currents, a symmetric and an asymmetric one has accepted since the 1960s. The existence of a symmetric equatorial ring current was concluded from Dst.Expand
